Description
Stores the stop error status of the CPU module of each station. (Including
own station)
OFF: All stations normal
ON: Stop error occurs to some stations
When a stop error has occurred on a station, each station status can be
checked in CPU operation status of each station (1) (SW0100 to SW0107).
Depending on the link refresh timing, CPU operation status of each station
(1) (SW0100 to SW0107) and the update may be offset by one sequence
scan.
(Condition)
• Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error is held.
Stores the continuation error status of the CPU module of each station.
(Including own station)
OFF: All stations normal
ON: Continuation error occurs to some stations
When a continuation error has occurred on a station, each station status can
be checked in CPU operation status of each station (2) (SW0110 to
SW0117).
Depending on the link refresh timing, CPU operation status of each station
(2) (SW0110 to SW0117) and the update may be offset by one sequence
scan.
(Condition)
• Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error is held.
Stores whether the error frame is received or not in the IN-side transmission
path of each station.
OFF: All stations receive no error frame
ON: Some stations receive error frames
When error frame reception is identified, each station status can be checked
in Current IN-side error frame reception status (SW0120 to SW0127).
Depending on the link refresh timing, Current IN-side error frame reception
status (SW0120 to SW0127) and the update may be offset by one sequence
scan.
(Condition)
• Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error is held.
